Pension Strategy - Gulf Expats & the 2027 IHT Change

Draw the pension down now, or leave it to grow?

For decades the answer was easy: leave the pension untouched, let it compound, and pass it on free of Inheritance Tax. From April 2027 that's gone. Unused pension funds now count towards your estate, and if you die after 75 the same money can be hit twice — 40% IHT, then income tax when your beneficiaries draw it. Meanwhile, sitting in the Gulf with an NT code, you can draw that pension down completely tax-free.

So which wins It comes down to whether you've truly escaped the UK tax net, how long the money would compound, and what your heirs would face. Run your numbers below.

// The case for drawing it down

While you're a Gulf tax resident with an NT code, withdrawals from a UK SIPP come out gross — no UK tax, and no Gulf tax either, since the UAE, Qatar and similar states don't tax foreign pension income. You take the money out clean and hold it outside the pension.

The point isn't to spend it. It's to get the capital out of a wrapper that, from April 2027, sits inside your estate for IHT — and to do it at a 0% rate you'll never see again once you're back in the UK tax system.

// The case for leaving it

A pension still grows free of UK income tax and CGT year to year. If you've genuinely shed long-term resident status, your worldwide assets — SIPP included — sit outside UK IHT entirely, and the wrapper keeps compounding untouched.

The catch is the long-term resident test. If you've been UK-resident for 10 of the last 20 years, you're still in the IHT net — and stay there for a tail of 3 to 10 years after you leave. Leaving the pension untouched only wins if you're truly out.

Spreading withdrawals over several years keeps you within the gross NT-code drawdown and avoids drawing attention. The model assumes each tranche stays tax-free in the Gulf.

// 02. Your IHT Position

Since April 2025, UK Inheritance Tax follows residence, not domicile. This is the single biggest driver of the result.

Non-pension assets (property, ISAs, cash) that consume the nil-rate bands before the pension is tested. The pension is taxed on top.

// 03. After You're Gone

If you die after 75 and leave the SIPP intact, your beneficiaries pay income tax at their marginal rate when they draw what's left. Pick the band you expect them to be in.

Once drawn out, the cash is reinvested somewhere — a GIA, an ISA, an overseas structure. This is the effective annual drag on its growth from dividend tax and CGT. ISA-heavy or low-yield holdings sit near 0%; a fully-taxable GIA for a higher-rate payer sits nearer 25%.

Will the reinvested capital face IHT too?

If you're still a long-term resident, the reinvested cash is also in your estate — so drawing down doesn't dodge IHT, it just avoids the post-75 income-tax layer. The big wins come from genuinely leaving the IHT net, or routing into IHT-exempt structures.

Route A · Draw It Down Now

Empty the SIPP tax-free, reinvest outside

Withdraw gross under the NT code while Gulf-resident, hold the capital outside the pension wrapper.

Route B · Leave It Invested

Let the SIPP compound, pass it on

Leave the pension untouched to grow, and let it pass to your heirs on death.

Each line shows what your heirs would actually receive, after all tax, if death occurred in that year. The crossover point — if there is one — is the age beyond which leaving it invested stops paying off.

This calculator models the April 2027 pension Inheritance Tax change (Finance Act 2026), the residence-based long-term resident IHT regime in force since April 2025, and the post-75 income-tax-on-inherited-drawdown stack. It uses HMRC 2026/27 thresholds (nil-rate band £325,000, residence nil-rate band £175,000, IHT 40%). It assumes you can secure and maintain an NT code for genuinely tax-free Gulf drawdown of a private pension — this does not apply to UK government service pensions. It does not model the temporary non-residence "5-year rule" on returning to the UK, currency risk, or the loss of future tax-free growth inside the wrapper beyond the reinvestment-drag input. It is a planning tool, not regulated financial or tax advice. The interaction of the LTR tail, double-tax treaties and your specific scheme rules can change the picture materially — get advice from a fee-only chartered tax adviser before acting.

Methodology & Sources

How the maths actually works.

This is a genuinely hard decision, and the honest answer is "it depends." What it depends on is laid out below, along with every rule the calculator applies and where it comes from.

Why this question only appeared recently

For years, the smart move with a UK pension was to leave it alone. It grew free of income tax and capital gains tax, and when you died it sat outside your estate — so your family inherited it without Inheritance Tax. The standard advice was to spend everything else first and touch the pension last, because it was the most tax-efficient thing you owned.

Two changes pulled that apart. First, from April 2025 the UK switched from taxing Inheritance Tax on the basis of domicile to taxing it on the basis of residence — which dragged a lot of Gulf expats who thought they'd left the net firmly back into it. Second, from April 2027 unused pension funds count as part of your estate. Put those together and the pension went from your most IHT-efficient asset to potentially your least. That's the whole reason this calculator exists.

The April 2027 pension IHT change

From 6 April 2027, most unused defined contribution pension funds and pension death benefits are counted as part of the deceased's estate for Inheritance Tax. Anything above your available nil-rate bands is taxed at 40%. This was confirmed in the Autumn Budget 2024, refined through consultation, and legislated in the Finance Act 2026. Funds passing to a spouse or civil partner stay exempt, as do death-in-service benefits.

The brutal part is what happens if you die after 75. The pension is taxed twice: 40% IHT comes off the fund as part of your estate, and then your beneficiaries pay income tax at their own marginal rate when they draw whatever's left. Stack a 40% IHT charge on top of 40% income tax on the remainder and the effective rate on that money runs to roughly 64% — commentary in the sector puts the combined hit in the 64–67% range, and higher for the largest estates. The calculator applies this stack automatically whenever your "plan to age" is 75 or over.

The long-term resident trap — the bit most people get wrong

Here's the assumption that catches people out: moving to Dubai does not, by itself, get you out of UK Inheritance Tax. Since 6 April 2025, the test is residence, not domicile. If you've been UK tax resident for at least 10 of the previous 20 tax years, you're a "long-term resident" and the UK taxes your worldwide assets — your SIPP very much included — no matter where you actually live.

And leaving doesn't switch it off straight away. There's a tail. If you were resident for 10 to 13 of the last 20 years, you stay in the IHT net for 3 full tax years after you go. That tail stretches by one year for every extra year of residence, up to a maximum of 10 years for the longest-resident leavers. Only after the tail expires — or after 10 straight years of non-residence, which resets the clock — are your non-UK assets genuinely outside the net.

This is why the calculator's first real question is whether you're a long-term resident. If you are, the leave-it route gets taxed on death and drawing down early starts to look attractive. If you've genuinely served out your tail and you're fully clear, leaving the pension to compound tax-free is much harder to beat. The toggle flips the entire result, which is exactly how much this single fact matters.

Why the drawdown can be tax-free at all

Left to its own devices, a UK pension provider slaps emergency PAYE tax on every withdrawal. The way round it is an NT (No Tax) code. You prove you're tax-resident in the Gulf, claim relief under the relevant Double Taxation Agreement using HMRC's Form DT-Individual, and HMRC instructs your provider to pay you gross. Because the UAE, Qatar, Bahrain and similar states don't tax foreign pension income, the money is then genuinely untaxed in both countries.

One important limit: this works for private pensions and SIPPs, which the treaties make taxable only in your country of residence. It does not work for UK government service pensions — civil service, armed forces, police and many teachers — which stay taxable in the UK regardless of where you live. The calculator assumes a private SIPP. If your pension is a government one, the drawdown route loses its tax-free footing and the comparison changes completely.

How the two routes are modelled

Draw it down now. The model takes the pension out in equal tranches over the number of years you choose, all tax-free under the NT code. Each tranche is reinvested and grows at your assumed rate minus a "reinvestment drag" — the annual tax cost of holding the money outside a pension, which you set. If you're still in the IHT net and the reinvested cash sits in your estate, it faces 40% IHT above your bands on death. But there's no income-tax layer, because the money is already out of any pension wrapper.

Leave it invested. The pension grows at the full rate with no tax drag while you're alive. On death, from April 2027 it enters your estate and faces 40% IHT above your bands. If you die at 75 or older, the post-IHT remainder is then taxed as income at your beneficiaries' marginal rate — the stack. The calculator shows the combined effective rate so you can see how punishing it gets.

Both routes are then compared on one number that actually matters: how much reaches your heirs after every layer of tax. The chart plots that figure for every year between now and your plan age, so you can see whether and when one route overtakes the other.

What the calculator deliberately leaves out

A few things are out of scope, and you should hold them in mind. It doesn't model the temporary non-residence "5-year rule" — if you draw down hard while abroad and then return to the UK within five tax years, those withdrawals can be retroactively taxed, which would wreck the drawdown case. It doesn't handle the 25% tax-free lump sum (PCLS) separately, currency risk on a sterling pension funding a dollar-pegged life, or the precise length of your IHT tail. And it assumes you can keep the NT code running cleanly for the whole drawdown period.

None of these are reasons to ignore the result — they're reasons to treat it as a starting point for a proper conversation with a fee-only chartered tax adviser, rather than a final answer. The decision is reversible in one direction (you can always draw down later) but not the other (you can't un-draw a pension), so the cost of getting it wrong is asymmetric. Model it carefully.
